centrotherm SiTec, a subsidiary of centrotherm photovoltaics said that it had received Final Acceptance Test (FAT) from Shaanxi Tianhong Silicon Industrial Corporation (STSIC) of a turnkey 1,250MT polysilicon plant. centrotherm SiTec was also in the in process of commissioning a second polysilicon expansion at STSIC that would take capacity to 3,000MT using state-of-the-art 24-pair reactor technology, according to the company.
Ongoing collaboration includes optimization of production processes to reduce energy consumption, a key cost in polysilicon production.
centrotherm SiTec also noted that it was working with STSIC on fully integrated manufacturing systems through ingot to solar cell production. First ingots successfully produced were said to have taken place in mid-2011.
Two solar cell production lines with a total of 60MW of annual capacity are also currently being commissioned.
